Ok, first of all, you're starting software engineering training, so you're now one of those "nerd *ssholes". And the whole point behind security measures is to act as a deterrent to criminals, the risk and effort required to get what they want being less than any possible reward. If I left $10,000 just sitting out in a big pile on a table somewhere, someone will steal it. Its not a lot of effort for a big reward. If I have a cash card with $50 on it in a locked box, no one is really going to bother, its lots of effort for almost nothing. So anytihng you can do to make it harder to get at your stuff is going to put people off stealing it.
